Publication number: 20150129052Abstract: A yard hydrant, including a discharge nozzle above ground level, connects to other vertically reciprocal working parts in the ground below the frost line. A water storage chamber, disposed below the frost line, is formed in part by a deformable diaphragm.

Publication number: 20150129068Abstract: The present disclosure provides air-tight mechanical valves. In a general embodiment, the valves include a shaft and a segmented sleeve. The shaft includes a plurality of shaft ports distributed around a circumference of the shaft. The sleeve is configured to fit concentrically around the shaft and includes a body having at least two body pieces, at least one internal seal, and at least one set of a plurality of sleeve ports distributed around a circumference of the body. The plurality of sleeve ports cooperates with the plurality of shaft ports to facilitate fluid flow. The valves of the present disclosure advantageously reduce losses of pressure and compressed air during use.Type: ApplicationFiled: May 15, 2013Publication date: May 14, 2015Inventors: James Arnau, Marc Bilodeau, Robert Leone, Glen Wright

Publication number: 20150129070Abstract: Methods and apparatus to bias spool valves using supply pressure are disclosed. An example apparatus includes a housing of a spool valve, the housing including a first port to receive a fluid at a supply pressure. The example apparatus further includes a spool within the housing. A position of the spool is to be selectively controlled via an input force acting on the spool, the position of the spool to define a path of a flow of the fluid through the spool valve from the first port to a second port of the housing. A biasing force is to bias the spool opposite the input force, the biasing force to be generated from the supply pressure applied to an end of the spool.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Inventors: Richard Jay Winkler, Christopher Steven Metschke, Bradley Dale Busse

Publication number: 20150129071Abstract: A rotary shear valve having three-point stator seating is provided. Three contact points are predetermined between a bottom of the stator and a valve body rim and three clamping pads may also be predetermined. The three clamping pads and the three points of contact between stator and the valve body rim are corresponding and aligned when the rotary shear valve is assembled so that the clamping or compression forces on both sides of the stator directly oppose one another, thereby effectively canceling each other. In one embodiment, the stator includes three contact points on the bottom surface proximate the periphery of the stator to contact the valve rim and a gasket includes three clamping pads proximate the periphery of the gasket web to apply a compression force on the top surface of the stator above the three contact points.Type: ApplicationFiled: May 11, 2012Publication date: May 14, 2015Applicant: SIEMENS HEALTHCARE DIAGNOSTICS INC.Inventors: Edward Francis Farina, Nicholas Michael Shmel, JR.

Publication number: 20150129072Abstract: A biasing force adjustment device includes: a cylindrical component having a first thread part; a reciprocate component accommodated in the cylindrical component; a biasing portion that biases the reciprocate component in a first direction; and a biasing force adjustment component that adjusts a biasing force of the biasing portion. The biasing force adjustment component has a second thread part engaged with the first thread part so as to control the position of the biasing force adjustment component relative to the cylindrical component, and a regulation part that regulates movement of the biasing force adjustment component relative to the cylindrical component by being deformed in a radial direction by external force applied in the first direction.Type: ApplicationFiled: November 10, 2014Publication date: May 14, 2015Inventors: Tetsuya HARA, Norihisa ACHIHA, Hiroyuki NAKANE, Masaki AIHARA
